    <p>When getting a json from a URL I only want to work with it, when the data is valid.</p> <p>my approach so far by using <a href="https://github.com/douglascrockford/JSON-js" rel="nofollow">JSON</a>:</p> <pre><code>$http.get( 'data/mydata.json' + "?rand=" + Math.random() * 10000, {cache: false} ) .then(function (result) { try { var jsonObject = JSON.parse(JSON.stringify(result.data)); // verify that json is valid console.log(jsonObject) } catch (e) { console.log(e) // gets called when parse didn't work } }) </code></pre> <p>However before I can do the parsing, angular already fails itself</p> <blockquote> <p>SyntaxError: Unexpected token { at Object.parse (native) at fromJson (<a href="http://code.angularjs.org/1.2.0-rc.2/angular.js:908:14" rel="nofollow">http://code.angularjs.org/1.2.0-rc.2/angular.js:908:14</a>) at $HttpProvider.defaults.defaults.transformResponse (<a href="http://code.angularjs.org/1.2.0-rc.2/angular.js:5735:18" rel="nofollow">http://code.angularjs.org/1.2.0-rc.2/angular.js:5735:18</a>) at <a href="http://code.angularjs.org/1.2.0-rc.2/angular.js:5710:12" rel="nofollow">http://code.angularjs.org/1.2.0-rc.2/angular.js:5710:12</a> at Array.forEach (native) at forEach (<a href="http://code.angularjs.org/1.2.0-rc.2/angular.js:224:11" rel="nofollow">http://code.angularjs.org/1.2.0-rc.2/angular.js:224:11</a>) at transformData (<a href="http://code.angularjs.org/1.2.0-rc.2/angular.js:5709:3" rel="nofollow">http://code.angularjs.org/1.2.0-rc.2/angular.js:5709:3</a>) at transformResponse (<a href="http://code.angularjs.org/1.2.0-rc.2/angular.js:6328:17" rel="nofollow">http://code.angularjs.org/1.2.0-rc.2/angular.js:6328:17</a>) at wrappedCallback (<a href="http://code.angularjs.org/1.2.0-rc.2/angular.js:9106:81" rel="nofollow">http://code.angularjs.org/1.2.0-rc.2/angular.js:9106:81</a>) at <a href="http://code.angularjs.org/1.2.0-rc.2/angular.js:9192:26" rel="nofollow">http://code.angularjs.org/1.2.0-rc.2/angular.js:9192:26</a> angular.js:7861</p> </blockquote> <p>How can I prevent angular from throwing this error or how else should I handle verifying the JSON ?</p> <p><strong>UPDATE: Solution:</strong></p> <pre><code>$http.get( // url: 'data/mydata.json' + "?rand=" + Math.random() * 10000 , // config: { cache: false, transformResponse: function (data, headersGetter) { try { var jsonObject = JSON.parse(data); // verify that json is valid return jsonObject; } catch (e) { console.log("did not receive a valid Json: " + e) } return {}; } } ) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
